FEED-WATER APPARATUS.

SPECIFICATION forming part of Letters Patent No. 262,721, dated. August15, 1882. Application filed April 14, 1882. (No model.) i

To all whom it may concern:

Be it known that we, FRANK S. ANDERSON and CHARLES SAUER, of Easton, inthe county of Talbot and State of Maryland, have invented a new andImproved Feed-Water Apparatus and Alarm for Boilers, of which thefollowing is a full, clear, and exact description.

The object of our invention is to furnish a reliable feed-water governorfor boilers, and one that shall also give alarm when the waterfalls'below the safety-line.

The invention consists in a combination of cylinders and a float, ashereinafter described and claimed.

Reference being had to the accompanying drawings, forming part of thisspecification, in which similar letters of reference indicatecorresponding parts in both the figures, Figure 1 is a sectionalelevation of the feed-water governor and alarm, and Fig.2 shows theparts separately.

A is a hollow cylinder of metal, provided with steam-tight heads a a,and fitted with water and steam pipes b b at top and bottom, by which itis to be attached to the boiler.

B is a second hollow cylinder, contained in the cylinder A, and somewhatsmaller, so as to give space between the two. This inner cylinder isheld by the caps a a, and is provided at its end with perforations b b,that allow free passage of steam and water.

0 is a float fitting snugly in cylinder B, so as to rise and fall withthe water-level.

t t are vertical guides on which the float moves. The guides t are usedto insure fit of the two ball-valves, and are provided with spiralsprings to preserve the float from any sudden jar or movement that mightcause it to rise or to fall, and thus open the steamways when notdesired. These springs can be tightened or loosened, as required, by thenutsson the guides, as shown.

d is a steam-pipe extending from the upper part of cylinder B through.the upper head, a, and formed atits lower end with a seat, 6, for aball-valve, f, that is attached on the upper end of the float.

g is asecond and smaller ball-valve, attached on the float by means of aspiral spring, h, and t is a steam-pipe formed at its lower end with aseat for the valve 9, and extending through whistle, k.

D is a cylinder attached to the lower end of the cylinder a, and fittedwith a piston, l, and a rod, 'n, that is connected for stopping andstarting the feed pump or injector.

p is a spiral spring in the cylinder D, around rod n, for returning thepiston. 0 is an adjustable head for tightening and loosening the springp.

E is an injector of any suitable construction.

p is a glass gage fitted on the side of the cylinder A for indicatingthe height of water.

In operation, when the water in the boiler is at the highest point ofsafety, the valve f is upon the seat at the lower end of the pipe d, andsteam is thus cut off from the cylinder D. As soon as the water-levelfalls steam passes to the cylinder D, and by pressure on the pistonloperates the rod a and sets the in jectorin operation. Water being thusforced into the boiler, the level is raised and the float rises. At thesame time the valve f moves to its seat and cuts off the steam. Thevalve 9 of the whistle-pipe will not leave its seat until the float hasfallen far enough to allow full expansion of the spring h, therebypreventing an alarm when the feed-water apparatus is in order; but incase the injector should fail to work, and the water-level be therebybrought down below safety-point, the whistle-valve will leave its seatand the whistle will be blown.

This apparatus, it will be seen, is entirely automatic in its operation.It may be usedin connection with any form of boiler, and will keep thewater at nearly one point at all times, never allowing the level tolow-water mark except when the feed-water apparatus is out of order,when the alarm will be sounded. This will insure a saving of fuel, as asteady fire can be maintained at all times and under all circumstances.It is especially useful with agricultural and plantation engines, forwhich expert engineers are not usually employed.

The inner cylinder, B, is used to still or quiet the water and preventunsteadiness of the float.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. The feed-water governor consisting of cylinders A and B, float O,valve f, and steam- 5. In feed-water apparatus, the cylinder 1),provided with spring-cushioned piston l and rod 11, connected forstopping and starting feed-Water-feeding devices, combined with thecylinder A and the inner apertured cylinder, 13, containing a float thatrises and falls with the water-level in the boiler, substantially asdescribed.
